    I don’t know typescript. But if that’s the case, this meme doesn’t make much sense.

    Who writes the types of variables in a language with type inference unless forced by the compiler?

      Maybe it’s a language without type interference?

      Either way, it sometimes makes sense in TypeScript to help the type system out a little bit.

      let array: string[] = [];

      In this situation, the type system can’t infer that the empty array should be a string array, because there are no items to go by.
